Optimisation of the punching process on the TruPunch 1000 machine
Kudláč, Lukáš ; Dvořák, Milan (referee) ; Peterková, Eva (advisor)
Content of this bachelor thesis is the suggestion of optimisation of punching process on the TruPunch 1000 in Limid Mohelno s.r.o. Case of device for induction heating is manufactured from steel DC01 with thickness 1 mm. To manufacturing of the evolved shape was as the most advantageous technology determined the punching technology. Principle and fundamentals of punching are described in the theoretical part of this thesis. In the practical part is suggested optimisation including technical and economical evaluation and comparison of the prices for original and new suggested process.

Multifunctional object - analysis of substructures of the structure
Pelouch, Adam ; Šulák, Pavel (referee) ; Švaříčková, Ivana (advisor)
This Bachelor thesis deals with design and evaluation local supported ceiling slab made from reinforcement concrete of polyfunctional building. The ceiling slab of the second floor was designing. Internal forces were analysed in RFEM software based on finite entity method with check of usability results by equivalent frame method. Structure was verified according to ultimate and serviceability limit states. Then the comparation of results of direct design method and finite entity method on simple slab 5X5 span.

Manufacturing of Shaped Holes into Stamped Metal Sheet
Bartusek, Břetislav ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The aim of bachelor thesis is a proposal of a new technology for manu-facturing of shaped holes into stamped metal sheets. The sheets are made of stainless steel DIN 1.4301 of thickness 0.8 mm. Square holes will be punched into a half-finished metal sheet with pre-pressed lengthwise stamps where elastic-plastic deformations occur. On the basis of study of the sheet metal forming technology, technological calculations and the machine adaptation, a new technology is proposed. The new technology is unassuming both with respect to machinery and tool equipment in a mechanical engineering factory. Also it enables solutions of dimensionally variable die stampings with stamps in higher quality for minimum costs. As the forming machine a punching press, model LDR 25-A, was chosen.

Production covering grids of welding machine
Rous, Miroslav ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
This thesis has been written in the time of my bachelor studies and it describes a production design of a rear cover of a welding set. It focuses on manufacturing of ventilating holes in this component. The cover is made of steel of standard quality 11 320, 1 mm thick. The flattened out shape of the component will be stamped on a Finn Power SG6 machine and subsequently it will be bent on a press brake Safan DNCS 225-4300. The practical part of this thesis contains a design of an instrument making the ventilating holes and an economic assessment.

Design of the floor slab structure of a tall building
Vintrová, Tereza ; Šimůnek, Petr (referee) ; Zich, Miloš (advisor)
The bachelor thesis deals with the design of the ceiling structure of a high-rise building. The basis for the work was a study of the building with basic floor plan dimensions and heights. The aim of the bachelor thesis is to design a locally supported floor slab with a stiffening core in the middle, as a section of one floor, namely the ceiling above the tenth floor. According to the specified study, a slab model was created in SCIA Engineer to analyze the internal forces based on which the design of the flexural reinforcement of the slab to the ultimate limit state was carried out. The design of the shear reinforcement is based on the internal forces of the 3D model and was done using Schöck Bole with manual verification of the selected column. Non-linear calculation of the 3D model and manual verification of crack widths was used to assess the ultimate limit state. At the end of the work, the design of the circumferential rib variant and the comparison of the two types of slabs was carried out. The work includes a static calculation and drawings.

Reinforced concrete structure
Zdražilová, Pavlína ; Matušíková, Anna (referee) ; Šulák, Pavel (advisor)
This bachelor thesis deals with design and assessment of chosen parts of load-bearing reinforced concrete cast-in-place structure of a department store. The aim of this thesis is to design and assess the reinforced concrete structure of a slab above first floor and one column. Scia Engineer 14 computational software was chosen to model the structure and to obtain the international forces. The structure is designed according to ČSN EN.

Structure of multi-storey building
Achillesová, Jana ; Klodner, Jan (referee) ; Perla, Jan (advisor)
This diploma thesis deals with the project of the structure of ferroconcrete multi-storey building. Selected parts for assessment are point-supported slab over the 1st floor, inside column, external and internal wall in the 1st floor. Finite Element Method in software Dlubal RFEM 5.23 was selected for the analysis. Another part of the thesis is the project of dimensions of foundations that are dealt with as deep foundations in accordance with engineering-geological survey.

Sugar storage tank
Kotík, Libor ; Musil, Jiří (referee) ; Zich, Miloš (advisor)
The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization of construction process. The aim of this work is to the design of the main components based on the required storage capacity tank, mechanical properties of the stored material and technical amenities.
